Artco mounted grinding wheels are developed especially for grinding hard steels, such as those used in the mold & die industry, as well as other hard metals. Aluminum oxide grains are held firmly in place by a vitrified or ceramic-type bond and securely cemented to a steel shank. The grains are free cutting, allowing for greater stock removal combined with longer wearing life.

Artco mounted wheels are color-coded by grits BROWN = 60 grit, BLUE = 80 grit, WHITE = 100 grit. The brown wheels are recommended for non-hardened steels or other hard metals. Blue mounted wheels have a slightly finer grit and hold up well in the small points. White wheels are recommended for heat-treated steels, being both finer in grit and softer in the bonding. Dimensions refer to diameter x length.
